Oriental Journal of Chemistry is a peer reviewed quarterly research journal of pure and applied chemistry. It publishes standard research papers in almost all thrust areas of current chemistry of academic and commercial importance. It provides a platform for rapid publication of quality research papers, reviews and ch…
The influence of plasmonic effect on the upconversion emission characteristics of Yb 3+ –Er 3+ –Tm 3+ tridoped β-NaYF 4 hexagonal microrods is studied. Upconversion spontaneous emission can be improved by 10 times if the microrod is deposited on an Ag-coated substrate. The enhancement is also dependent on the emission…
This study is aimed at evaluating the effects of triclosan-encapsulated halloysite nanotubes (HNT/TCN) on the physicochemical and microbiological properties of an experimental dental composite. A resin composite doped with HNT/TCN (8% w/w), a control resin composite without nanotubes (HNT/TCN-0%) and a commercial nano…
Configuration interaction cluster calculations have been performed to investigate the electronic structure of orthorhombic distorted ${\mathrm{SrVO}}_{3}$ compound, where a considerable tetragonal crystal-field splitting of larger than $180\phantom{\rule{4.pt}{0ex}}\text{meV}$ for ${t}_{2g}$ orbital levels is suggeste…
We report a new bimetallic cyanido-bridged trinuclear complex [Cu II (enpnen)] 2 [Mo IV (CN) 8 ]·6.75H 2 O ( 1 ) (enpnen = N,N ′-bis(2-aminoethyl)-1,3-propanediamine) that shows reversible photomagnetic effect. The photo-induced increase of magnetization is characterized by the irradiation temperature-dependent shapes…
Abstract NiMoO 4 /Ni 3 S 2 /MoS 2 (NiMoSO) composites have been successfully synthesized by a simple hydrothermal process based on NiMoO 4 , and a series of NiMoSO/rGO with different weight rate of rGO were also prepared. The morphology, crystal structure and formation of the NiMoSO/rGO10% were characterized by SEM, T…
In applications, surface states and bulk doping concentration are important parameters of inorganic semiconductors, as they determine the bulk properties and substantially influence the properties of interfaces in devices, foremost the electron energy level alignment. In this work, we provide a qualitative model to de…
OBJECTIVE: It is difficult to identify the gold nanoparticles (AuNPs) intracellularly due to their non-fluorescent nature. Although gold can quench the fluorescence of any fluorophore, hence it is also difficult to combine gold with a fluorophore such as a semiconductor quantum dots (QDs). The aim of this study was to…
Co2−xMn1+xSi films with various composition x were epitaxially grown using molecular beam epitaxy (MBE). High crystallinity and atomic ordering in the prepared Co2−xMn1+xSi films were observed, and their magnetic damping and anisotropic magnetoresistance (AMR) effect were systematically investigated. An ultra-low magn…
Integration of graphene into electronic circuits through its joining with conventional metal electrodes (i.e., gold) appears to be one of the main technological challenges nowadays. To gain insight into this junction, we have studied the physicochemical interactions between SiC-supported graphene and a drop of molten…
Abstract Periodically hydrogenated graphene is predicted to form new kinds of crystalline 2D materials such as graphane, graphone, and 2D C x H y , which exhibit unique electronic properties. Controlled synthesis of periodically hydrogenated graphene is needed for fundamental research and possible electronic applicati…
This research explores the extraction and characterization of natural fiber from the agro-waste of Lagenaria siceraria (LS) plant stem (commonly known as bottle guard). The extracted fiber from the waste stems has high cellulose content (79.91 %) with good tensile strength (257–717 MPa) and thermal stability (withstan…
New dioxomolybdenum(VI) complex [MoO 2 (L)(CH 3 OH)], where L is the dianionic form of N '- (3-bromo-5-chloro-2-hydroxybenzylidene)-4-nitrobenzohydrazide (H 2 L), was prepared and characterized by IR and UV-Vis spectra, as well as single crystal X-ray diffraction (CIF file ССDС no. 1567063). The complex crystallizes a…
Spin valve devices, the resistive state of which is controlled by switching the magnetization of a free ferromagnetic layer with respect to a pinned ferromagnetic layer, rely on the scattering of electrons within the active medium to work. Here we demonstrate spin-valve-like effect in the Ni-Mn-In thin films, which co…
Abstract Der Aufbau von diskreten, selbstorganisierten Architekturen in Wasser fand in den vergangenen Jahren erhebliches Interesse, da sich eine große Anzahl von Anwendungen aus ihrer definierten 3D‐Struktur ergibt. Dieser Aufsatz diskutiert die gemeinsamen Bemühungen von Chemikern aus der supramolekularen Chemie und…
The composites samples (1-x) (Cu 0 . 6 Zn 0 . 4 Fe 2 O 4 ) CZF + x (BaTiO 3 ) BT, where (x = 0%, 10%, 20%, 30%, 40%, 50% 60%, 70%, 80%, 90% and 100%), have been prepared by ball milling. The x-ray diffraction showed that two phases have retained their identity in the composites and no undesired reaction has occurred b…
The study investigated the laser lap welding of fuel cladding and end plug made of molybdenum (Mo) alloy. The research results showed that the tensile strength of the welded joint when a weld was located at the Mo tube was significantly larger than that at the fit-up gap between the fuel cladding and end plug. Moreove…
In this study, chitin was chemically extracted from the crayfish (Astacus leptodactylus) shells. Deproteinization, demineralization and decolorization processes were applied to obtain chitin. In order to determine characterization of the chitosan; yield, moisture and ash contents, degree of deacetylation, colour prope…
In this communication, we report on the disappearance of reflection color by photopolymerization of an acrylate monomer in lyotropic cholesteric liquid crystals from a cellulose derivative for color image applications. When a hydroxypropyl cellulose (HPC) derivative possessing propionyl side chains (HPC-Pr) was homoge…
